[PATCH v6 00/18] IR encoders and use for IR wakeup

[Sean Young <sean@mess.org>]

This series introduces IR encoders and also makes winbond-cir and
nuvoton-cir use the sysfs filter wakeup interface for programmable
IR wakeup.

To program hauppauge rc-5 remote power button for wakeup:

	cd /sys/class/rc/rc0
	echo rc-5 > wakeup_protocols
	echo 0x1e3d > wakeup_filter
	echo 0xffff > wakeup_filter_mask

Note that the wakeup API can change due to discussion[2].

Changes since v5:
 - fixed issue in img-ir filter code (thanks James)
 - nec32 issue fixed and verified against liquid tivo remote
 - renames space distance to pulse length
 - made all timing structs const
 - all encoders round-trip over rc-loopback

Changes since v4:
 - ImgTec now also uses wakeup_protocols; all rc drivers which do wakeup
   now use the same sysfs interface
 - Implemented all IR encoders except for xmp for which I cannot find
   useful documentation
 - ir_raw_encode_scancode() now takes u32 scancode, rather than a
   rc_scancode_filter, since it cannot encode a mask.
 - All encoders have been tested extensively by round-tripping over
   rc-loopback and generating random scancodes. No problems found
   other than known nec32 issue[1].
 - winbond-cir has seen more testing
